Sorry for the late response haha.
That makes sense! Im still stuck with my 7300 here.
One of these days Ill grab one of those 8800's but no clue when Ill be able to afford it, those Apple ones are still stupid expensive.. Times is tough so were staying in 32-bit land for awhile.

I have flashed PC cards in the past, but the last one, my FX5500 I was using in my old G4, lost some sort of heat sensor capability because of a kext you had to delete to make it work and it ultimately died a couple years later when it blew a cap on the board.. Im gonna guess it 'overheated' and popped so I never bothered with it again. Im pretty out of touch with that whole 'scene' now too, I should go look and see if theres anything newer I can go grab cheap at Newegg and flash.. I cant remember what but I know recently there was a game I wanted to get from the Apple Store and the graphics card was the one thing my system didnt have to run it.. Might have needed Mavericks/Mountain Lion too but if I had the card Id probably already be on Mavericks so I could upgrade to Logic Pro X finally..
At least MAME still works! Dont know what I would do without my emulators of all things haha!
